hello list, I am attempting to load balance SSL web servers using haproxy on centos 5.7. I am using HA-Proxy version 1.4.18 Here is the stanza in the config regarding SSL: listen https 192.168.1.200:443 mode tcp balance roundrobin option forwardfor except 192.168.1.200 option redispatch maxconn 10000 reqadd X-Forwarded-Proto:\ https

I''m looking for the most reliable setup for Mongrel. Reliable meaning avoiding things like sending too many requests to a single mongrel process, or sending requests to a mongrel process that has hung for some reason. The handler will most likely be rails, but it might be a custom handler. SSL is also a requirement, which limits the options a bit but it can''t be done away

Hello Mongrels, Building on the last messages about Fastthread, can we get a detailed survey of the different ways people are deploying their applications? It will help with near-future Mongrel development. Please include the following things: * Framework, if any (Camping, Merb, Rails, Nitro, Ramaze, IOWA, Rack...) * Mongrel version * Mongrel handlers used (rails, dirhandler, camping,

Hello All, Ticket #30 (http://mongrel.rubyforge.org/ticket/30) has a set of changes to mongrel that I''ve written on behalf of my employer, Raritan Computer, Inc. Also, these changes are released under the existing Ruby license used for Mongrel. Raritan is using mongrel internally for product development and was not able to get the level of scalability desired due to limitations

Which web server does mongrel fair best with? -Ron

Hi, I am new to clustering and loadbalancing in apache, What is best way of doing it? How do I do the clustering and what tools do I need to use? Do I have those tools, I use CentOS , Do i have any tools in CenOs which comes default in it? And how do I do apache load balancing? should I rely on apache forums or mailing list or is there any way or tool I can use in CentOS? Can any throw some vague

Just a quick question to those of you using merb and sequel or datamapper. How do you setup your merb app? For example: merb -X off -c 5, then run mod_proxy_balancer or nginx to load balance between the 5 (or whatever #) of merb nodes? merb -X off -d, then simply use something like proxypass merb -c 5, keep the mutex lock and cluster it haproxy, swiftiply, evented mongrel...... What

I''ve been having a mess of a time using this module, which stinks because its behavior is EXACTLY what I am looking for... whenever I bootstrap new rabbitMQ nodes I want to add them to our HAProxy instance. Here''s my relevant site.pp entries: node /^rabbit.*/ inherits basenode { @@haproxy::balancermember { $fqdn: listening_service => ''messaging00'',

Hi, This morning, while checking for a correct deployment, we found out that the Unicorns we are using were sending 500 Internal errors very frequently to the HAProxy that sits in front of them. After some investigation, It turned out that HAProxy checks the backend by opening and closing a connection to the unicorn. Unfortunately the Unicorns we use ( v 0.990.0 ) will try to reply to this probe

> btw, what is the reasong for NGINX proxy anyway? Since dovecot proxy can do this for you too. I want to do authentication using the IP that the IMAP client used to connect to the IMAP server. That is, I have 50 IPs, one for each state my users live in, so the users can only connect to the IMAP server using the domain name where their account is hosted (e.g., va.example.com

Hi guys, I''ve been chasing a problem in my web-stack: Lighttpd -> Mongrel -> Rails, and found a problem with the interaction of Lighttpd and Mongrel. If a request takes more than 5 seconds, Lighty will retry it - and then the requests / responses get mixed up in Lighty and it returns a bad response to the client. Not good. I''m convinced that the problem is

Hello all, I''m wondering if you deploy nginx: 1) on the same machine that runs unicorn (exclusively proxying to that) 2) on a different machine that doesn''t run unicorn 3) both, nginx could forward to either to localhost or another host on the same LAN And of course, the reason(s) you chose what you chose. I''m inclined to believe many folks are on 1) simply

Hello all, The question is not necessarily CentOS-specific - but there are lots of bright people on here, and - quite possibly - the final implementation will be on CentOS hence I figured I'd ask it here. Here is the situation. I need to configure a Linux-based network load balancer (NLB) solution. The idea is this. Let us say I have a public facing load balancer machine with an public IP

I?m trying to understand how the nginx mail proxy and dovecot work. As a I understand it, nginx can listen on a IP:port for IMAP connections. NGINX then can invoke a PHP script to do authorization and backend server selection. Does NGINX than proxy to the backend dovecot IMAP server all subsequent IMAP commands that the user?s mail client requests? Does the backend dovecot IMAP server do its

I know most people use pound, but has anyone tried using ultramonkey as a load balancing solution between a cluster of mongrels and lighttpd?

Hi all, Tried out the mongrel upload progress plugin with Drb and it works great on my OSX development box, but when putting it into production (Ubuntu Dapper), uploads complete but the app isn''t returning any values for upload progress, and uploads are not showing up in the queue when running upload_client.rb. Before anyone asks, yes, I''m running both the mongrel instances and

We''re using unicornctl restart with the default before/after hook behavior, which is to reap old Unicorn workers via SIGQUIT after the new one has finished booting. Unfortunately, while the new workers are forking and begin processing requests, we''re still seeing significant spikes in our haproxy request queue. It seems as if after we restart, the unwarmed workers get swamped by

Hi, I have a nginx server which is using the proxy protocol to forward tcp connections to dovecot. Dovecot is configured to be a submission service for email to be sent. Then postfix should send the email itself which is also using the ha proxy protocol. There are a few moving parts in this problem so I'm not sure where the problem is. But I want to ask if somebody can validate my dovecot

We have been searching for a Rails deployment architecture which works for us for some time. We''ve recently moved from Apache 1.3 + FastCGI to Apache 2.2 + mod_proxy_balancer + mongrel_cluster, and it''s a significant improvement. But it still exhibits serious performance problems. We have the beginnings of a fix that we would like to share. To illustrate the problem, imagine a

I''m using a cluster of mongrels behind an apache 1.3 proxy pass. I''ve been passing the request to pen, which in turn balances the cluster of mongrels. Now, I''d like to be able to use a different server to send the static files created by the rails application, so I tried to replace pen with nginx. Everything seems to work fine except the environment variable REMOTE_ADDR.
